Natural regeneration in a mixed fir and spruce stand (Abieti – Piceetum) was researched on the areas damaged by spruce bark beetles and reclaimed by clear cutting. The damage occurred in 2003 due to poorly applied forest order. All the infested and dead, mainly spruce trees, damaged by spruce bark beetles (Pityogenes chalcographus and Ips typographus) were removed by clear cutting in the form of irregular circular areas. The degree of regeneration, abundance and the characteristics of fir and spruce young growth were studied depending on the aspect of the regeneration areas and their sizes. Natural regeneration of fir and spruce stands after the reclamation of the damage caused by bark beetles should be adapted to a specific management system, because the differences in fir and spruce bioecological characters require different silvicultural procedures depending on the actual state. By the application of clear cutting in the form of circular areas with eccentric extensions, the conditions of spruce natural regeneration can be improved in the aim of achieving the technical goals of management of mixed fir and spruce forests.
